  • Abstract
    Readout of a Rogowski coil is affected by external magnetic fields e.g. from the energizing transformer and the return current conductor. The influence of these external magnetic fields on the reading of a high precision Rogowski coil was measured. The results are used to estimate the achievable uncertainty in calibration of current transformers up to 10 kA.
